The strike is over grading and pay related to a programme of modernisation and training within the service
A 24 hour strike by ambulance workers is underway.
A long running dispute between the National Ambulance Service and unions have led to around 2,000 workers walking off the job today.
EMTs, Paramedics and Advanced Paramedics are preparing to strike.
The row is over grading and pay related to a programme of modernisation and training within the service.
SIPTU says its ambulance members have been left with no option but to strike.
The HSE is warning of potentially long delays to non-life-threatening call outs.
However the 999 service is operating and priority is being given to emergency cases.
